To me for a kung fu film the plot didnt need to be overtly intricate, they all have interconnecting goals Q.T. style..
Thaddeus= Feels awful that the weapons he made for the Lion Clan where used in a horrible way. He also wants to free Lady Silk from the whore house by buying her out from Madame Blossom. He also seeks revenge against Brass Body
Jack Knife= Hired to make sure the governor's gold makes it through Jungle Village to another village in the north.
X-Blade= Revenge seeker against Silver Lion for a henious crime.
All while the other clans contact Thaddeus to make them weapons to steal the gold
